These gains seem rather small for calves that were fed as liberally 
as these, but when the exceedingly droughty summer with the re- 
sulting poor pastures is considered the calves did very well. The 
calves of lot 2, which were fed a heavier grain ration than those of 
lot 1, made the larger gains.

It is seen that the calves of lot 1 required 247 pounds of cotton- 
seed cake in addition to grass to make 100 pounds of gain in weight, 
and the calves of lot 2 required 126 pounds of cottonseed cake and 
250 pounds of shelled corn for producing 100 pounds of gain in 
weight. When the feeds are charged at market prices and pasture 
at 50 cents per head for each 28-day period it cost $5.04 and $6.58 
to make 100 pounds of gain in live weight on the calves of lots 1 and 
2, respectively. 
The calves were valued at 5 cents a pound on May 5, when the 
experiment began, the cost per head at that time being $16.65 for 
lot 1 and $17 for lot 2. The cost of the concentrate fed during the 
summer was $9.50 per calf for lot 1 and $16.08 per head for lot 2. 
There was a pasturage charge of $3.20 per head for the calves of 
each lot for the summer. The total cost per calf in the fall of the 
year (October 30, 1916) was $29.37 for lot 1 and $36.27 for lot 2. 
The average cost per hundredweight in the fall was $5.02 for the 
calves of lot 1 and $5.73 for the calves of lot 2. 
At this time the calves of lot 2 were in much better shape than 
those of lot 1, but the calves of each lot had been growing consid- 
erably and were not well enough finished to be marketed at this time. 
As they were not fat enough for market on October 30 and the 
grass was very short, it was decided to put the calves in the dry lot 
and feed them corn silage for roughage and continue the grain ration 
the same as when the calves were on pasture until they were finished.
